Abstract: ABSTRACT OF THE DISCLOSURE Compounds are described of the general formula:                     wherein:          R1 is acyl of the formula -C(=O)-R5; R2, R3, R4, R6, R7 and R8 are each selected from the group consisting of hydrogen and acyl of the formula:                     -C(=O)-R5 wherein R5 is selected from the group consisting of alkyls, substituted alkyls, alkenyls, substituted alkenyls, cycloalkyls, substituted cycloalkyls, arylalkylenes, substituted arylalkylenes, alkylenecycloalkyls, alkylene substituted cycloalkyls, alkynyls, substituted alkynyls, aryls and substituted aryls, wherein R2, R3 and R4 are selected such that at least one of R2, R3 and R4 is an acyl.          When R2, R3 and R4 include one or more acyls that are not identical to the acyl of R1, these compounds of formula I are novel compounds.  The invention also includes processes to produce the compounds of formula I.          Compounds of formula I complex and/or chelate tissue tri-valent ions, especially iron and aluminum (Fe+++, Al+++), when administered to a human being, and are therefore useful in therapy in the treatment of diseases in which tissue ion levels in the body have increased or toxic levels.  These iron-related diseases include, for example, thalassemia major, sideroachrestic anemic, Blackfan-Diamond anemia, aplastic anemia, sickle cell anemia, hemolytic anemias and hemosiderosis brought about by multiple blood transfusions including treatment for the anemia accompanying conditions requiring kidney dialysis. Aluminum-related diseases or conditions include Alzheimer's disease, senile dementia and dialysis encephalopathy.

Abstract: S P E C I F I C A T I O N     Inventor:   Stephen V. Chelminski Title:      Method And Apparatus For Converting An Air Gun Into A Hydro Gun For Marine Seismic Impulse Generation ABSTRACT OF THE DISCLOSURE     A marine air gun is advantageously converted into a hydro gun by substitution of two clamp rings and by convenient addition of various parts, allowing normal air gun firing by trig-gering with usual solenoid valve.  In a presently preferred embodi-ment, a novel firing chamber is also substituted, providing out-wardly-facing piston rings and cylinder encircling this chamber.          A special clamp is substituted for that which normally secures operating chamber to firing chamber.  An outer-cylinder-defining housing is concentric around the firing chamber, with an annular piston sliding in the annular cylinder space defined intermediate the firing chamber and the new outer housing.  This annular piston is propelled by the air blast, suddenly ejecting water slugs from ports in the new outer housing.  Also added is a pressure-con-trolled air-vent valve, responsive to air pressure coupled through passages in an adapter mounted between solenoid valve and air gun.          This vent, held closed by pressurized air during firing, after-wards vents to atmosphere.  Advantageously it conserves firing-chamber air; it now enables ambient water pressure automatically to return the annular piston to initial position. By virtue that the air gun can be fired in usual manner and by virtue of auto-matic return of the annular piston after each firing, the usual firing and control systems and usual air compressors are used on shipboard, thereby creating large economies and time savings resulting from convenient conversion to hydro gun action or con-venient conversion back to air gun action, whenever desired.  In a modified embodiment of the invention, the air vent valve can be totally eliminated.  The inertia of the water in an air vent line in communication with the upper end of the outer annular cylinder space has been found to be sufficient for momentarily preventing significant escape of pressurized air up into the air vent line during firing, thereby advantageously maintaining the desired high air pressure within the hydro gun structure during firing, without the need to provide a pressure-controlled air vent valve.  The lower portion of the air vent line is preferably made of metal and may have exterior fins for readily conducting heat from the am-bient water into the interior of the vent line for preventing in-ternal ice build-up resulting from chilling due to rapid air ex-pansion in the vent line near the exit from the upper end of the outer annular cylinder space.

Abstract: Abstract An electromagnetic flow meter has two magnetic poles (6, 7) attachable to a measuring tube from the outside.  Its core section (10, 11) is connected at the radially outer end without a gap to the adjoining magnetic system portion (14,  15).  The separating gap (17,  18)  is disposed beyond the magnetic path for the stray flux.  Further, the separating gap (17, 18) extends over a larger area than does the cross-section of the core section (10, 11).   In this way, induction in the separating gap drops and the structural size of the magnetic system can be reduced.          Fig. 1.

Abstract: ABSTRACT OF THE DISCLOSURE An FSK demodulator which does not require intricate adjustment and eliminates the limitation on usable frequencies is described.  The demodulator includes a clock generator for generating clock pulses and a signal converter for converting an FSK signal having an analog level to a digital signal having a predetermined level.  A first logic circuit gates the clock pulses in response to an output signal of the signal converter.     A second logic circuit inverts an output signal of the signal converter.     A third logic circuit, reset by an output signal of a fourth logic circuit, counts output signals of the first logic circuit.  The fourth logic circuit is reset by an output signal of the second logic circuit, for counting the clock pulses.  A fifth logic circuit receives an output signal of the third logic circuit at a first input terminal, the clock pulses at a second input terminal and an output signal of the fourth logic circuit at a third input terminal.  The fifth logic circuit temporarily memorizes the output signal of the third logic circuit.  A sixth logic circuit receives an output signal of the fourth logic circuit at a first input terminal and an output signal of the fifth logic circuit at a second input terminal, and provides a demodulation signal.

Abstract: Abstract of the Disclosure An electrochemical measuring cell is disclosed wherein the diffusion membrane which separates the electrolyte from the ambient is made of an intrinsically-conductive and electrochemically active plastic.  This way the diffusion membrane itself defines the measuring electrode of the measuring cell.  This is a substantial advantage over known electrochemical measuring cells wherein the measuring electrode is defined by an electrically conductive layer applied to the surface of the diffusion membrane facing toward the electrolyte.  By making the diffusion membrane from an electrochemically active plastic, a removal of the electrically-conductive layer from the diffusion membrane is prevented.

Abstract: ABSTRACT           A contact tip for supporting a consumable welding electrode and for supplying welding current thereto.  The contact tip is generally rod-shaped and has a passage with a helical contact surface.  The welding electrode is fed through the passage and makes electrical contact with the contact tip.  Because of the helical contact surface, the passage never becomes constricted by cumulative deposits of dirt and extraneous matter from the welding electrode surface.  Also, the helical contact surface, which axially extends at least one complete turn, has an unbending effect on the welding electrode, thus straightening the electrode.          A distance "A" of the electrode axis from the contact tip axis may be chosen, as desired, considering the diameter of the welding electrode.  Optionally, the contact tip may include a sleeve-like nozzle, to shield the contact tip from deposits of welding splatter.
